Struggling to build a circuit to test a 30ua Moving Coil Meter properly

To get an accurate shunt value you need to know the meter coil resistance.you could install a shunt across the meter so it will take a larger current for full scale deflection.
Go for half scale deflection or less to start:I was thinking of testing the movement with a resistor in series from a 1.5v battery but can't get the math to add up properly.
Meter Resistance is 3250ohms. Its quite a rare movement so don't want to kill it
